I do not know a lot about Hafner trains so I am not sure if this is the correct tender/locomotive pair, but the tender is the one that is in this picture with the #2000 locomotive.
Steve and Jim - if either of you has a spare I would be very grateful.
Thanks.
looks correct for the 2000 loco (turn it around). Same frame as the BX32 boxcar and the Plastimarx tenders.
